2d
2-Dimensional
take, for an example, a duck. This is a 3d shape because it has three dimensions. Compare this to a square, which is 2d. the difference is that the duck has a beak, and the square does not.
dodecahedron
Dodecahedron.
least volume and most surface area is 3D triangle
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
That will depend on what they are but in general 3D shapes have surface area and volume whereas 2D shapes have only surface area.
It is the total surface area of the shape.
A pentagon is a 2D shape. Volume and Surface Area is only found in 3D shapes.
the area of a 2D shape with dimensions 8cm and 12cm is 96cm2, but if you're talking about surface area of a 3D shape then you need the other dimension.
a face.
a sphere :)))
A 3d shape can have infinite sides
because for a 3d shape you use surface area which is the same except you calculate the area of each side and then add them together
